INTRODUCTION Lung cancer is the leading cause of malignancy-related deaths in Hungary, involving complex surgical and oncological treatment. AIM Factors influencing the tolerability of complete/planned and incomplete postoperative chemotherapy after surgery were analyzed. METHOD During a 6-year period (January 1, 2011-December 31, 2016), data of 72 patients operated with lung cancer (adenocarcinoma and squamous cell carcinoma), receiving complete (4 cycles) and incomplete (<4 cycles) postoperative chemotherapy were analyzed. The following factors among the two groups [complete: n = 53; incomplete: n = 19] were analyzed: gender, mean age, body mass index, Malnutrition Universal Screening Tool, Charlson Comorbidity Index, second malignant tumor, atrial fibrillation, Forced Expiratory Volume 1 sec, Performance Status, open/Video-Assisted Thoracic Surgery (VATS) lobectomy, duration of surgery, postoperative fever, need for transfusion, prolonged air leak, redo surgery, histology, tumor stage. RESULTS The rate of complete postoperative cycles obtained from logistic regression analysis, were substantially higher after VATS lobectomies [n = 26 (83.87%)] compared to open procedures [n = 27 (65.85%)]; (p = 0.092; OR = 0.356), without significance. Multivariate analysis (open/VATS lobectomy, upper/middle-lower lobe resection, diabetes, prolonged air leak, postoperative fever) showed significantly increased successful uptake of complete cycles after VATS (p = 0.0495), while upper/middle lobe resections (p = 0.0678) and the lack of diabetes (p = 0.0971) notably increased the number of complete cycles, without significance. CONCLUSION Twenty-six percent of patients were unable to receive complete planned postoperative chemotherapy. VATS lobectomy patients received significantly higher number of complete cycles of postoperative chemotherapy. Diabetes and lower lobe lobectomies had a negative effect on the tolerability of postoperative chemotherapy. Orv Hetil. 2018; 159(19): 748-755.
